LOCK.

SPECIFICATION forming part of Letters Patent No. 602,518, dated April 19, 1898.

Application filed March 11, 1897l Serial No. 627,015. (No model.)

.To @ZZ wwnt t may concern:

Be it known that weVILLIAM A. PETIT and ELIJAH H. MILLER, citizens of the United States, residing at Stephensport, in the county of Breckenridge and State of Kentucky, have invented certain new and useful Improvements in Locks; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention is in the nature of an improved bag fastener or lock; and it has for its object to provide a lock of this character of a very simple and inexpensive nature.

It also has for its object to provide a lock of this character which cannot be opened without the use of a suitable key and which can be readily adapted for use as a mail-bag lock.

lVith other objects in view, 'which will be hereinafter referred to, ourinvention consists in the peculiar combination and novel arrangement ot parts, such as will be first described in detail and then specifically pointed out in the appended claim, reference being had to the accompanying drawings,in which- Figure 1 is a perspective view of our improved lock, showing the same adapted for use as a mail-bag lock. Fig. 2 is a top plan view thereofwith the cap-plate removed. Fig. 3 is a transverse section thereof, taken on the line 3 3 of Fig. 2. Fig. 4 is a similar section showing the hasp member engaging the lock members on their under or beveled end. Fig. 5 is a transverse section taken on the line 5 5 of Fig. 2. Fig. G illustrates a form of key used in connection with our lock, and Fig. 7 is a detail view of the hasp member detached.

ln its practical construction our improved lock comprises ahousing, consisting of a baseplat-e 1, having an elongated opening 2 for the passage of the hasp member, hereinafter referred to. The bottom plate 1 has its sides turned up to form vertical flanges et, which eX- tend from a point near the end 5 beyond the pivotal end of the lock-levers 6, such bottom plate also having end portions turned up to form vertical guides 7 and horizontal lianges 8, which ianges S are, however, only usedV when the lock is used as a bag-fastener.

By turning up the ends of the base-plate to form vertical guides and terminating such guides in the manner shown in Figs. 1 and 2 lock-seats 9 and 10 will be produced to receive the turned-down ends 11 and 12 of the top or cap plate 13, which is thus held from endwise 'movement on the bottom plate by the seats 9 extension l of the base-plate, the side edges being held from flapping or turning upward by the overturned lian ges 8 of the side portion 7, thereby providing a positive movement for holding the end of the strap from turning up at its point of connectionpwith the lock, the side member 7 of the bottom plate also forming one edge of the seat 10, which receives the end 12 of the cap-plate.

The locking means proper comprise a pair of pivoted jaws 6, secured at one end 6a to a pivoted post 17 and having their outer angle or lock members 6a normally held to a closed abutting position by the flat springs 18, se cured at one end to the jaw and having their free end held to bear against the side walls of the housing, suitable stops 2O being also provided to limit theV inward movement of the lock member 6.

It will be noticed by reference to Figs. 3 and 4 that the under edges of the lock end of the member (ia are beveled or inclined, as at 6b, whereby when the hasp is inserted they will automatically separate, the upper end of the hasp being made bevel, as at 3, to admit of an easy operation of the several parts in the manner stated.

As it is desirable in practice to have the housing as shallow as possible, the cap-plate is provided with a raised or hood portion 13 to receive the upper end of the hasp when the parts are in their locked position, as clearly shown inFig. 3. The plate to which the hasp member is attached is of sufficient width to completely cover the opening 2, to

thereby prevent the manipulation of the lockv by the insertion of an implement through suchropening 2.

Y The cap-plate has a keyhole of suitable shape, and the base-plate 1 a key-pin 10, hav- IOO ing suitably-arranged wards ld to admit of the unlocking of the lock by means of a properly# formed key only.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the operation and the advantages of our improvement will readily appear. The same is of very few parts, which can be economically manufactured, readily assembled, and which will effectively and positively serve their intended purposes.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

A lock, comprising a housing consisting of a bottom member having vertical upturned side anges 4, horizontally-inturned flanges 8, at one end, the seat 9; and the seat l0, disposed between the flanges 4 and S, said bottom having a hasp engaging lock devices held wit-hin the housing adapted to automatically open and close on the hasp, a cap-plate having angle ends adapted to engage the seats 9 and lO, and provided with a keyway, and a hasp all arranged substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
